Anomaly: Without normalization, redundancies occur in the table, and it may lead to errors or some sort of inconsistency. These are termed as anomalies. Anomalies occur when user wants to update the data in the table. There are three types of anomalies namely, Insertion anomaly, Deletion anomaly and Modification anomaly. Data redundancy: Data redundancy is presence of repeated data in the storage device. It consists of duplicate data that is additional to the actual data. In this, the data related to a folder can be seen in other folders. For example, file related to science folder can be seen in mathematics or social.
